Alex Smith out for rest of game with concussion

With a little under three minutes left in the first half, quarterback Alex Smith left the field for the locker room. Team officials announced that he has a concussion and has been ruled out of the remainder of the 49ers’ game against the Rams.

Smith took a hard hit to the head early in the second quarter when he slid into Rams linebacker Jo-Lonn Dunbar, although he did continue to play afterward. He was replaced by Colin Kaepernick late in the second quarter while being assessed by team doctors on the sideline. Smith was then escorted off the field.

Smith was 7-of-8 with a touchdown. The 49ers went into halftime down 14-7.
